The Mercedes-Benz Viano (W639), particularly the facelifted version introduced in 2010, represents a significant offering in the mid-size multi-purpose vehicle (MPV) segment. While not officially sold in the United States, the Viano was a popular choice in Europe as a premium alternative to vans like the Volkswagen Multivan and Ford Galaxy. Positioned above the smaller Vito, the Viano catered to buyers seeking a blend of passenger comfort, cargo versatility, and a touch of luxury. The W639 generation, produced from 2003 to 2014, underwent a notable facelift in 2010, bringing updated styling, improved interior features, and refined engine options, including the 2.2-liter CDI diesel engine discussed here.
Mercedes-Benz Viano (W639) CDI 2.2 L: An Overview
The Viano CDI 2.2 L, produced from September 2010 to March 2014, was a key variant within the W639 lineup. It focused on providing a balance between fuel efficiency and adequate performance for its intended role as a family vehicle or executive shuttle. The “CDI” designation signifies a common-rail direct injection diesel engine, a technology Mercedes-Benz pioneered to improve fuel economy and reduce emissions. This model typically accommodated six passengers and featured five doors, offering flexible seating configurations and ample cargo space. Its rear-wheel-drive layout was standard, contributing to a more refined driving experience compared to front-wheel-drive MPVs.
Engine & Performance
The heart of the Viano CDI 2.2 L is the OM 651 DE 22 LA, a 2.143-liter (130.77 cubic inches) inline four-cylinder diesel engine. This engine produces 163 horsepower at 3800 rpm and 360 Newton-meters (265.52 lb.-ft.) of torque between 1600 and 2400 rpm. The turbocharger and intercooler enhance performance by forcing more air into the engine, improving combustion efficiency. Power is delivered to the rear wheels via a six-speed manual transmission. Acceleration from 0 to 100 km/h (0-62 mph) takes 12.1 seconds, while 0 to 60 mph is achieved in approximately 11.5 seconds. The Viano CDI 2.2 L reaches a maximum speed of 188 km/h (116.82 mph). The engine’s power-to-weight ratio is 12.1 kg/Hp, and the torque-to-weight ratio is 5.5 kg/Nm.
Design & Features
The W639 Viano boasts a minivan body style, characterized by its spacious interior and practical design. The 2010 facelift brought a more contemporary front fascia with a redesigned grille and headlights. Inside, the Viano prioritized comfort and versatility. The cabin could be configured with various seating arrangements, including individual seats, bench seats, and even swiveling captain’s chairs. Standard features typically included air conditioning, power windows, and a basic audio system. Higher trim levels offered options like leather upholstery, navigation systems, and advanced climate control. Safety features, crucial for a family vehicle, included ABS (Anti-lock Braking System) and a robust body structure. The Viano’s dimensions – 5008 mm (197.17 in) in length, 1901 mm (74.84 in) in width, and 1875 mm (73.82 in) in height – provide a substantial footprint, maximizing interior space. The wheelbase measures 3200 mm (125.98 in).
